The Oster Cryogen-X Elite Clipper Blades are coated with titanium carbonitride. Starting with a consistent 62 HRC (hardness on the Rockwell "C" scale), they are put through an innovative process. You end up with an edge that is over an 80 HRC with coatings that will not flake off, and blades that will last much longer. Titanium 10- medium /Titanium 40- For Clipping Surgical Area.
Oster Elite Cryogen-X clipper blades are designed to stay sharp longer and not wear down as easily. Great for use on any of the Oster clippers.
